3 Claims.

The present invention relates to latches particularly adaptable to articles of jewelry employing a pin for a `fastening means, as on brooches and the like.

This is a divisional application of an application led by the undersigned on January 10, 1944, and designated by Serial Number 517,647.

An object of this invention is to provide a novel and improved latch for brooches and similar articles, which is easy to lock and unlock.

Another object hereof is to provide a novel and improved latch means of the character mentioned, in which the pin point is shielded while the latch is closed.

A further object of this invention is to provide a latch of the type mentioned which has a novel and improved locking means.

Another object hereof is to provide a novel and improved article of the character set forth, which is reasonably cheap to manufacture, simple to manipulate and efcient in carrying out the purposes for which it is designed.

Other objects and advantages will become apparent as this disclosure proceeds.

To accomplish these objects, essentially, a pivoted pin is otherwise moveably mounted on a frame carrying a socket for receiving the free end of the pin, and means to prevent movement oi the pin when within the socket.

In the accompanying drawings forming part of this application, similar characters of reference indicate corresponding parts in all the views.

Fig. 1 shows a side elevation of an open latch embodying the teachings of this invention.

Fig. 2 is a similar view, partly in section, showing the latch in closed condition.

Fig. 3v is a top plan view of Fig. 2; said Fig. 2l being a section taken at lines 2-2 in Fig. 3.

In the drawings, the numeral 2| designates a frame adapted to carry an ornament (not shown) Apin 22 is pivotally mounted at 23 to a link 24, which in turn is pivotally mounted at 30 to the bracket 28 w'hich extends from said frame. The axis pin or stud 23 also carries thereon pivotally mounted, a cam member 25 which is adapted tok be shifted by handling prong 26', so that said cam frictionally engages the bracket member 28, to lock the pin against movement after the pointed end of the latter is set within the socket member i5. It is evident that by turning cam 26 away from engagement with the bracket member 28, the latch may be opened. It is preferable that link 24 be comparatively short, and pin 22 relatively long. Also to be noted is that the socket l has an entrance slot 3| to guide the pin 22 within the socket bore 32.

This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desired that the specic description herein be deemed illustrative and not restrictive and `that the patent shall cover all patentable novelty herein disclosed; reference being had tothe following claims rather than to the particular embodiments herein to indicate the `scope of this invention.

I claim:

1. In an article of the character described, a frame, a link pivotally mounted at one of its ends on the frame, a pin pivotally secured at one of its ends to the other end of the link; the axes of rotation of the pin with respect to the link and of the link with respect to the frame being parallel, a socket element carried by the frame, adapted to receive the freeend of the pin, a cam element carried pivotally on the link, adapted to be manually shifted to frictionally engage the frame when the free of the pin is within the socket, whereby said pin is maintained against movement about its aXs with respect to the link;

2. An article as dened in claim 1, wherein the pin socket element is provided with an entrance slot communicative with the socket bore, whereby the free end of the pin after entering the slot, will be guided thereby into the socket bore.

3. An article as dei-ined in claim 1, wherein the pin and cam element are pivotally mounted on the link, about a common axis.
